Analog Devices Inc. EVAL-AD7626EDZ

Overview

EVAL-AD7626EDZ from Analog Devices is an evaluation board designed specifically for the AD7626 16-bit, 10 MSPS PulSAR® analog-to-digital converter. It provides buffered parallel (16-bit) and LVDS serial interfaces, on-board 4.096 V reference (ADR434), clock oscillator, FPGA-based deserialization, and configurable analog signal conditioning for high-fidelity data acquisition testing.

For engineers reviewing the EVAL-AD7626EDZ datasheet, EVAL-AD7626EDZ hardware setup, EVAL-AD7626EDZ software interface, or EVAL-AD7626EDZ compatibility with EVAL-CED1Z, this page delivers verified board-level specifications, functional context, supply support, and manufacturer-integrated design rationale - all aligned with Analog Devices' official evaluation platform documentation.

Technical Context

The EVAL-AD7626EDZ implements a complete ADC evaluation system centered on the AD7626's 10 MSPS throughput, differential input architecture, and flexible echo-clock LVDS interface. It integrates an ADA4932-1 single-ended-to-differential driver, dual ADA4899-1 unity-gain buffers, and an EP3C5F256C7N Cyclone III FPGA for real-time LVDS deserialization to match the parallel interface of the EVAL-CED1Z capture board.

Signal path flexibility includes jumper-selectable amplifier supplies (±5 V / ±7 V), reference source selection (internal, ADR434, or ADR280-derived 1.2 V), and front-end configuration between SMB-connected differential inputs (J1/J2) and optional 50 Ω-terminated single-ended sources - all validated per Analog Devices' schematic and test procedure documentation.

FAQ

What is the primary purpose of the EVAL-AD7626EDZ evaluation board?

The EVAL-AD7626EDZ is a dedicated evaluation platform for the AD7626 16-bit, 10 MSPS analog-to-digital converter. It enables full characterization of dynamic performance (SNR, SINAD, THD, SFDR), DC accuracy (code transition noise), and interface functionality - including both LVDS serial and 16-bit parallel outputs - using Analog Devices' official software and the EVAL-CED1Z capture board.

Which host interface does the EVAL-AD7626EDZ require to operate?

The EVAL-AD7626EDZ requires the EVAL-CED1Z capture board as its host interface. It connects via a 96-pin DIN edge connector (P4) and relies on the CED1Z for USB 2.0 PC communication, buffered BUSY/WR/RD handshaking, and analog power distribution (+12VA/–12VA/+5VA/–5VA). No standalone USB or PCIe interface is provided on the EVAL-AD7626EDZ itself.

Does the EVAL-AD7626EDZ support both differential and single-ended analog inputs?

Yes - the EVAL-AD7626EDZ supports both configurations. By default, it accepts fully differential signals via SMB connectors J1 and J2, routed through ADA4899-1 buffers. For single-ended sources, jumpers JP1, JP2, JP6, and JP9 can be reconfigured to route the signal through the ADA4932-1 driver, implementing a 50 Ω-terminated, unity-gain inverting differential stage with 0.5× gain.

What reference options are available on the EVAL-AD7626EDZ?

The EVAL-AD7626EDZ offers three reference configurations: (1) internal AD7626 4.096 V reference (P13 open), (2) external ADR434 4.096 V reference (P13 set to REF, P6 to "4.096V"), or (3) internal AD7626 reference buffer driven by ADR280 1.2 V (P13 to REFIN, P6 to "1.2V"). All paths are validated in the board's schematic and user guide.

Can the EVAL-AD7626EDZ be used without the EVAL-CED1Z board?

No - the EVAL-AD7626EDZ is not a standalone instrument. It lacks onboard USB, microcontroller, or data storage and depends entirely on the EVAL-CED1Z for digital interface, clock distribution, power sequencing, and PC communication. The 96-pin interface (P4) is mechanically and electrically designed exclusively for mating with the EVAL-CED1Z.
